New submission from Ivan Johansen: In Python/importdl.c around line 99 in the function _PyImport_LoadDynamicModule() you can find the code: def = PyModule_GetDef(m); def->m_base.m_init = p;
If the module m, which is returned from a newly imported extension, is not created by PyModule_Create() but in some other way then PyModule_GetDef(m) will return NULL. The next line will then dereference a NULL pointer and crash. I suggest a check for this is added: def = PyModule_GetDef(m); if(def != NULL) def->m_base.m_init = p; ---------- messages: 192845 nosy: Padowan priority: normal severity: normal status: open title: Crash when extension does not use PyModule_Create() type: crash versions: Python 3.1, Python 3.2, Python 3.3, Python 3.4, Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18426> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
